f 'oIL BURNER.

Application lgd April 9, 1923. Serial No. 100,905. I

My objects, generally stated, are to provide for the more nearly complete gasification of the oil, thereby attaining greaterheating efficiency of the fuel and producing a cleaner and more effective llame with the elimination of the production of free carbon; to providea novel, simple and inexpensive construction for accomplishing these results, more especially in a natural-draft o burner; to provide for the supporting of the burner in the position necessary to occupied for accomplishing the most effective results; and other objects as will be manifest from the following description.

Referring to the accompanying drawings:- l l Figure l is a view in side elevation of my improved burner, illustrating it as installed in a furnace shown in sectional` elevation.

.o Figure 2 is a plan view thereof. Figure 3 is a view in sectional elevation of the burner, the section being taken at the hne 3-3 on Fig. 2 and viewed in the direction of the arrows. Figure 4 is a broken section taken g5 at the line 4--4 on'Fig. 3 and viewed in the directionof the arrows; and Figure 5, a broken sectional view taken at the hne 5 on Fig. 2 and viewed in the direction of the arrow.

The burner, in accordance with the preferred illustrated embodiment of my invenf tion, comprises a base portion and a superposed manifold portion 11 shown as supported thereon, the base portion v10 being formed at its center with an inverted bell portion 12 presenting a receptacle 12 and containing at opposite ends thereof apertures 13 surrounded by continuous flanges 14 shouldered, as represented at v15, and forming seats for a purpose hereinafter-- described.

The bell portion 12 at the center of the receptacle 12* contains a-screw-threaded opening 16 in which a pipe 17 is screwed to pro-l ject upwardly and downwardly at its opposite ends beyond the portion 12, the side wall of the pi e 17 where it extends above the base of t e portion 1.2 being apertured, as

represented at 18. Surmounting the pipe 17 and vertically spaced from the portion l2 isa burner-head inthe form of a generator late 19 preferably of the circular stepped orm, as shown, witlithe upper surface of each annular step portion annularly grooved, as represented at 20. The late 19, which is preferably fastened to the urner-section 10,

as by screws 19", engaging pairs 19" of ears 19, o n the plate 19 and screwin into the openings in diametrically-oppose lu 10b formed on the walls of the receptac e 12, is centrally apertured, as represented at l21, into which the open up r end of an oil-pipe, 22'is screwed, the oil to plied to the upper surface of the late 19 through this pi e-which latter exten downwardly throug the pipe 17, and in spaced relation thereto, as shown.

The pipe is screwed at-its-lower end into the opening 23 of a cross-itting24, the

gasied being suplower opening 25 in which has screwed into it a threaded pipe-section 26 which latter is screwed atits lower end into an opening 27 in a T-fittin 28 screwed at an opening 30 therein on e up r end of a pipe 29 supported as hereina ter described.A

1 The manifold section 11 is of general inverted U-shape and seats at its inlet end rtions 31 and 32 upon the seats 14 of the bouse member 10, the section 11 containing between its ends a tubular downwardly-projecting outlet portion 33 communicating with the interior of the manifold, and arranged concen- -tric with the generator late 19 and in vertically spaced relation ereto. It ma be here stated that the purpose of the manifold section 1l in so far as it has been described,

is to conduct air, as for example air drawn into it by the natural draft of the furnace in which the burner is located upwardly a ainst surfaces which are heated `by the burning of the fuel, and thence `downwardly against the generator plate 19 for mixture with the oil supplied to this plate, it being preferred that the inner surfaces ofthe manifold section 11 beprovided with a series of substantially parallel fins 34 and 35 to enhance the heateffect on the air and reinforce theimaniin fold t0 ensure that it presents the desired 'flo . s ace-below and surrounding the .'nected with a drain pipe 45 screwe I fold 11.

'opening inlets located at diagonally'oppose corners of the base member 10.

The purpose of the conduits 36 and 37 is to ldirect air supplied thereto, as by the natural draft through the furnace ulpped with the burner, through courses so isposed that the air is heated and thereupon, according to the preferred illustrated embodiment of m invention, conducted into and through the tting 24 and pipe 17 and thence into the f enerator p ate 19, for heating the oil as it ows upwardly through the pi e 22 and furnishing a suppl of heated air low and around the burner ead and sup lementary to that supplied thereto from a ve through themani The oil pipe 22 which extendsat its upper end through the coupller 24 and ipe 17 as, stated, is shown as aving a su stantiall horizontally f disposed portion 22 whic projects through the opening 44 ofthe T- coupler 28 in spaced -.relation to the walls of this opening, the coupler 28 bein coninto the opening 44 and through which the portion 22l of the pipe extends in spaced rela tion to the latter. The upper end of the pipe 29J is closed, as for examfple bg a plug 46, whereby should oil over ow 0m the plate 19, as for example in case of extinguishment of the'ilame and the continuing of thesupplyin of oil to the plate, it will drain through t e'openings 18 into the pipe 17 and thence outthroughthe pipe 45. T e

apparatus is referably provided with dripv bucket-contro led mechanism operating autohung on atrip lever 47 controllin matically in the-event of overflow through the ipe 45, to shut off the supply of oil to the urner. Such a mechanism, which is well known in the art and therefore need not be detailed, is diagrammaticall illustrated in Fi 1 in which the bucket or receiving the oi is represented at 46 and is showp as a s iutv oi valvelocated at the portion 48 o the pipe section 22 and controlling the flow of oil to the enerator plate.

' The burner structure illustrated alsocomprises a supporting base 49 having an up- 'wardly extending` socket portion ,50 into t in operative position, is

which the lower end of the pipe 29 extends and `to which it is secured, to permit of its l ,enterthe burner through the drain furnace, in anyidesirable way'. Inlthe arrangement shown the burner structure,

,which is located centrally of the side wall 53 of the furnace, rests at thesc-rews 52 upon the floerrepresented at 54 and uponwhich 7g I the furnace is supported. The annular space between .the base member 10 of the burner and the side wall of the furnace may be. filled in with any suitable material, as for example tire clay or cement composition re resented at 55 and confined in a' trou shaped annular receptacle 57 located in is v'space and supported, as for example by the stack, causes air to pam. u

to which the oil is supplied. The raft 'fefered to also causes air to enter the de ndin inlets 42 and 43 of the pipes 36 and 3 whic discharge into the space Abelow and around' the generator plate 19.- As the manifold and air conducting pipes referred to are subjected to the heat generated by the burning fuel, the air flowin throu h the coursesthus provided, becomes highly cated and in such heated condition is sup lied to the oil at the generator plate 19 t ereby augmenting the gasification of the fuel, preventing the production of free carbon and. causin a clean and'intense'ilame to be produced. urthermore' by positioning the'oil pipe 22 as shown anddescribed, it is subjected to the heated air flowing throu h the pipe 17,and thus lthe oil is' more readily gasi plate, .with the manifest advantage.v

The feature of providingthe adjustable legs 52 for the burner structure, is of ad vantage, especiallyv in the type of burner shown and described and involving a generator plate over which the oil, to be burned, flows, inasmuch as it is essential for the most effective operation of the burner that this plate extend horizontally, to ensure an even distribution of the oil over it, and such positioning of the plate maybe effected in applicants apparatus, re ardless of unevennesses existingin the burner is supported.

Thefeature of connecting the drain pipe 45 with the pipe through which heated air is introduced into the burner structure and providing this pipe with the o nings 18, is of advantage inasmuch as suc air as may pipe 45 becomes mingled with the heated air supplied through the pipes 36 and 37 and is thus tempered.
